摘要：
The invention provides a method to produce primary diamines by catalytic conversion of diols having a linear main chain of from 4 to 31 carbon atoms into the corresponding diamines. The reaction is conducted in a liquid or supercritical phase and is catalyzed by a homogeneous ruthenium-containing complex. The primary diamines obtained may be suitable for polyamide syntheses.
